IMPROVEMENT IN MAGAZINE COOKING-STOVES.

'Specification forming part of Letters Patent No. 1611, A41, dated June8, 1875; application filed l April 16, 1874.

To all whom it may concern:

Beit known that I, THoMAs N. CAULKINs, of Owasco, in the county of Oayuga and State of New York, have invented a new and useful Improvement inStoves; and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawingsand to the letters of reference marked thereon.

Figure 1 represents avertical section of my improved stove. Fig. 2represents a horizontal section of the'same. Fig. 3 represents a sideelevation, and Fig. 4 represents a horizontal section taken at line .r.fc of Fig. 3.

My invention embraces a combination of elements whereby the smoke,vapor, and gases generated in cooking will be carried out of the roomthrough the smoke-eduction flue, which communicates with thefire-chamber, and the combination and arrangement are such that the airdrawn into the stove to promote the combustion of the fuel will be takenfrom the upper portion of the room in which the stove is used, thusthoroughly ventilating the apartment.

Centrally located at the bottom of the stove below the grate there is anash-pit, M, surrounded with warming-ovens, O, -excepting the spaceoccupied by the door V. E denotes the coal-magazine, which is alsosurrounded with cooking-ovens N. The coal-grate surrounds the base ofthe cone H, and consists of a fixed ring of cogs, and a correspondingseries of cogs around the base of the cone. The apex of cone H extendsup to the center of the bottom of the coal-magazine E, which is providedwith a regulating cut-oi' or damper, g, provided with a handle or rodextending out at the bottom of the ovens N so as to be used to regulatethe draft and the admission of fuel to the grate below. The maincombustion-flue is an annular space around the firegrate, cone H, andbetween the upper plate of the ovens O and the 'bottom plate of theovens N, and this flue or combustion chamber connects with the fourvertical flues f, which at their upper ends connect with the fourhorizontal iues y above the ovens N. Surrounding the upper end of themagazine E a dome, D, is located, and the space between dome D and themagazine serves as a continuation of iiues y, and connects them with thesmokepipe L. F indicates a doorway, through which fuel is supplied tothe magazine E, and G denotes the air -induction pipe, which passes downthrough the elbow of the smoke-pipe L into the magazine, as representedin the drawings. A series of doors, s, are provided to give access tothe ovens N, and serve, when open, as horizontal hearths, upon whichvessels may rest when desired. Suitable holes are made through thebottom of ovens N communicating with the main combustion-flue, in whichvessels can be placed for cooking or heating; and small vent-holes aremade through the upper plate of ovens N, through which vapors, gases,Src., will be drawn and allowed to escape with the smoke from the fire,which finally escapes through the eduction-pipe L. The pipe G, throughwhich the air is supplied to promote combustion, passes down through thestove-pipe L and the dome D, and is connected with the upper part ofmagazine E. Being thus located the lower part of this pipe G is heatedby the concentrated heat from the iirechamber as it enters the dome D,and thereby thedraft of air is increased in force and volume that passesdown through the coal-magazine to the main re-chamber between the twotiers of ovens O and N.

Having described my invention, I claim and desire to secure by LettersPatent- 1. The combination of the two series of ovens O and N, the maincombustion-chamber between them, the liues f and y, and the dome D,substantially as described, for the purpose set forth.

2. The combination of the air-pipe G, the eduction-pipe L, and the domeD, in the manner and for the purpose specified.

THOMAS NEWTON OAULKINS.
